Pull request overview
This PR adds a defense-in-depth measure to the generated directory index.html pages by instructing search engines not to index the pages or follow their links, reducing the chance of directory structure exposure via crawling.
Changes:
- Added
<meta name="robots" content="noindex, nofollow">to the generated HTML<head>content. - Added a regression assertion in
MainTest.testGoEmptyDirto verify the robots meta tag is present in generated output.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head.Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence.Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.Result: REQUEST_CHANGES
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head670da38d5790daf3b18f7d8540d583caaf7cac13.Head SHA:

Closing as superseded by draft canonical #349. The same robots hint is retained there with the correct cooperative-indexing-only boundary and requirements for post-#363 update, current Google Search Central APA 7 doctoring, changelog, generated-page tests, exact-head checks, and independent approval. No review or check from this duplicate head is reused. |
Understood. Acknowledging that this work is superseded by #349 and stopping work on this task. |
🚨 Severity: MEDIUM
💡 Vulnerability:
생성된 정적 HTML 파일이 공개 웹 서버에 호스팅될 경우, 검색 엔진 크롤러가 이를 색인화하고 링크를 따라가 디렉토리 구조 전체를 파악할 수 있음. 이로 인해 정보 노출(Information Exposure)이 발생할 수 있음.
🎯 Impact:
공개 환경에서 의도치 않게 내부 디렉토리 구조나 파일 리스트가 검색 엔진 결과에 노출되어 악의적 사용자의 정찰 대상이 될 수 있음.
🔧 Fix:
생성되는 HTML
index.html의<head>섹션에<meta name="robots" content="noindex, nofollow">메타 태그를 추가하여, 검색 엔진 크롤러에게 인덱싱 및 링크 탐색을 하지 말 것을 지시함. (Defense in Depth)✅ Verification:
